Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 42,244,555, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 42,244,555 | |
| -1 | -42,244,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,244,555.
Example:
1 x 42,244,555 = 42,244,555
and
-1 x -42,244,555 = 42,244,555
Notice both answers equal 42,244,555
With that explanation out of the way, let's continue. Next, we take the number 42,244,555 and divide it by 2:
42,244,555 ÷ 2 = 21,122,277.5
If the quotient is a whole number, then 2 and 21,122,277.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 42,244,555 | |
| -1 | -42,244,555 |
Now, we try dividing 42,244,555 by 3:
42,244,555 ÷ 3 = 14,081,518.3333
If the quotient is a whole number, then 3 and 14,081,518.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 42,244,555 | |
| -1 | -42,244,555 |
Let's try dividing by 4:
42,244,555 ÷ 4 = 10,561,138.75
If the quotient is a whole number, then 4 and 10,561,138.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 42,244,555 | |
| -1 | 42,244,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 251 | 821 | 1,255 | 4,105 | 10,291 | 33,661 | 51,455 | 168,305 | 206,071 | 1,030,355 | 8,448,911 | 42,244,555 |
| -1 | -5 | -41 | -205 | -251 | -821 | -1,255 | -4,105 | -10,291 | -33,661 | -51,455 | -168,305 | -206,071 | -1,030,355 | -8,448,911 | -42,244,555 |
